I was thinking about doing my own fuel system and I thought I remember seeing something about a “how to” and thought someone might have a link to it. If not I was wondering if anyone might have done this or might have some suggestions such as how to plumb it and what pressures to run?

Do a little searching in the most recent archive. and you will find more ways to build a fuel system then you ever thought of. Particuarly posts made by GSP.
Are you looking to do a simple get rid of the factory pump and filter bowl system.
A 450hp lets go for a ride system,
or hold my beer and watch this system

To do one close to "Correctly" you will spend almost as much for parts as the Kit from Beans Diesel Performance. And save your self a lot of time and headache finding what you need.
You need to start with a through understanding of the stock system.

He has a very good point but it could be made for less depending on how you make it. You don't need garden hose for fuel line to make a nice functioning system.
just for information. Not saying it is the best way. But the setup i did to get my 4dr back on the rd after a mechanical pump failure uses factory hard lines up the frame to the engine, factory return, and factory selector. with 175cc injectors it drops 2psi at wide open throttle. A stock superduty pump is with a regulated return is good for about 425.
and it can be built for alot cheaper then a full out system. I purchased all the fittings and hose needed for the above described setup for under 100bucks.
Regulator around 135
Filter head with filter for under 50
I had some superduty pumps but they cant be more then 200. and if they are buy a aeromotive or something similar.

Thanks for the info! I don't think I need an all out fuel system right now. I think just getting the filter out from the valley and being able to control the fuel pressure would be a good start.I'm sure I could buy a great system from beans but I think I might enjoy makeing my own. It might cost more or less but it's nice when your done to step back and see what you made your self. Anyways what fuel pressure are you running? If you run higher pressure then you need what happens? o-rings fail? What is to high a fuel pressure?

Alaskan, Thanks for the pics they will help. I have a couple questions. It looks like you are feeding it from the front and returning from rear, any advantages? (I was going to do the same) Are you running one fuel tank or two, if two how are you switching tanks? What pressure are you running? Thanks again

No, I'm feeding to the rear and returning from the front into the regulator. Are you running one fuel tank or two, if two how are you switching tanks? A single Bronco tank because our selector valve is so small I just eliminated it and went with a single tankWhat pressure are you running?
60psi daily and 75psi on race day
Thanks again

No problem /ubbthreads/images/graemlins/wink.gif. Rick96F250 was a huge help while I was building mine and gave me a bunch of the ideas. Thanks Rick....

With the size of your lines I'm sure you keep the pressure at WOT. So you run from the tank to the fuel filter to the pump to the back of the head to the front of the head to the regulater back to the tank? From your pics it looks like you have two fuel pumps?

I have a 5/8" pickup, 5/8" line into 1 pre filter, two 3/8" lines into 2 Ele pumps, then into another filter, then two 3/8" lines to the back of each head, then the 3/8" from the front of each head to the Regulator, then 1/2" line from the Regulator to the tank. I knew "in my never ending quest for HP", that I'll be going bigger then the 250cc injectors one day and I never wanted lack of fuel to be an issue.

No way I just did a fuel system for a SD I know it's not a obs fuel system But BDP is to high for a fuel system you and do it your self for a lot cheaper

i did my own variation of the prepump tank mod, the majority of the eng stuff is from Swamp, the other Itp, and the rest my own stuff. I think I have 400 in the combined set up. The prepump alone was a huge eye opener as the pump i used to suck the tank empty was one of my 250 gph hot rod pumps, it struggled to empty the tank through the factory mixing valve set up and lines with all kinds of air in the fuel. After the 1/2" pick up the difference in flow through the huge pump was night and day along with zero air bubbles. The before pump flow and after with the stock sd pump was obvious. Take into account this is on my 99, but the same can apply for the obs.

He only used the big pump to pump the fuel out of his tank to drop it and do the intank mods, and then to prime his filter.

I saw your burnout but, when running do you use 4X4 or just your rears? I run in 4x4. I was having trouble hooking up in 4x4 si until I figured out the right combo on the tire Pressures, I figured I'd try "heating" the tires a bit to see if that helped /ubbthreads/images/graemlins/smile.gif
I didn't notice heavy tire spin on your actual
run. Quick truck. They look like pizza cutters on there. /ubbthreads/images/graemlins/biggrin.gif
265-75-16's but this year I'm going back to 35's

Why are you running two pumps? More volume?
[/ QUOTE ] It's not the volume I was after, I wanted to keep the PSI up under WOT because I was at 70 PSI at idle and at WOT it would immediately drop to 5-10psi with 2 different stock fuel pumps. So we started from the tank forward with a new fuel system
